I stitched together the floor plan for anyone interested. It was in MS Paint, so it's a bit rough but it should be helpful. (if that doesn't work it's at http://imgur.com/a/qrBb1)
More than likely the morning entrance will be from the queue hall (so the left "wall" of the queue hall is the entrance to the show floor). They'll probably open the south doors into the show floor once all the morning people are in.
Yeah, I'm just wondering about the route from the main hall to the galaxy/celebration stages and back.
If it works like Anaheim, then morning people will use a single entrance (that'll have multiple sets of doors) but then they'll open up other entrances once the queue hall is cleared.
